Working principle
By adopting the principle of laser scattering, through accurate optical design and gas path designed according to the principle of fluid mechanics, the particles in the sampled air can pAss through the beam successively with a high probability to produce weak scattered light. The scattered light is collected by an accurate optical signal collection device and projected onto a highly sensitive and high-bandwidth photodetector to obtain the signal intensity corresponding to the particles. The mAss concentration of the particles is calculated by the calibration procedure after conversion and aerodynamic calibration.
